I agree with Wondeer. The fact that Gravii considered going to Japan at all is not a good sign. It doesn't matter that she's not going anymore, but that she considered going in the first place which would imply the usage of a lot of money. Japan isn't exactly cheap, even with the cheapest possible tickets. There's food and housing and once you are in Japan, you'll probably want to buy souvenirs and stuff too. For example, she likes lolita stuff, yes? It is possible that in Japan, she might go shopping for lolita clothes and that isn't cheap either. Or just buy plushes or trinkets, etc, these are just examples. The plane ticket may have cost $800, but with everything else added on, food, shopping, housing, etc, it becomes well over $1k. And that just begs the question of, if she has this money, why can't she spare even 10% of it to refund her customers who have been left waiting for months? ):
As Wondeer said, this shows a poor ability to prioritize responsibilities. The customers she has left stranded by running away are people who have been hurt (and are quite justified in the hurt they feel) by this inability to prioritize and work, and this tweet among other actions as of late seems to indicate that if she is truly set on fixing things up, it is going to take a very long time and that she is still a novice in prioritizing, and that's going to be unfortunate for her and the people involved.
I'm also seconding Wondeer's recommendation to find a job, if possible, even if it's at a fast-food restaurant or something. Jobs tend to be more stable than depending on money from commissions unfortunately, and with her reputation as ruined as it is, it will probably be hard for her to get adequate commissions anyway. With a job, she can probably get a ,much more stable income, and with that, support herself (such as getting a new tablet) and also refund people. This would be a good situation for herself and the affected customers.
